To 1.71 whom i'trmat/ concern:

y Be it known that l', JoiiN A. Chinn', :i

citizen of the United States'. iwi-ling at ll'orcester, in the count)l of Worthner and State of lilassacliusetts, have inveiite'l eertaiii new and useful Iiiiproveiueiu`A in liabbiii-tpindles, of which the following i a speciiication.

My invention relates to iinprwft-iueuts in bobbin s iindleii. and particularly to a bolibin s indie having at one end tifo m' more annu ar projections to engage the holding jaws in the shuttle, which retain the spindle in the shuttle, and having at its other end an enlarged head to retain the lmhhin on the s iindle, and to furnish a bearing -utfave for t e iillin l as ity is drawn from the liobliin.

The o ject of my invention is to improve upon the construction of a bobhiii spindle of the description referred to, and more partieiilarl to provide a hollow lspindle, and a detaclia le retaining head for the end of the `spindle, made separate from and adapted to be removably secured to the Lpiudle.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

Referring to the rawings:-Figure 1 is a top view of a self-threading: shuttle of ordinary construction, having; spindle holding jaws, and showing;I a spindle embodying m v improvements combined thereivithmnd a sectional View of a filled `bobbin. on the spindie. Fig. 2 shows, on anonliirged scale, ii central longitudinal section-of the spindle and bobbin, shown in Fig. lf'detached, and, Fig. 8 corresponds to Fig. 2, but. shows. the removable retaining head, partially detached from the spindle, and the bcobin moved up slightly on the spindie.

In the aceonipiniyinq drawing, lis a self- -,itiireading shuttle, fiiv ich may be 'of any usual and well known construction, and provided with a air of yielding holding )uws 1'. in the usual) way.

The spindle embodying my improvements consists of the attaching end or bend 2. having thereon and in this instance made' integral therewith. three annular projections or ringe 2', adapted to extend between and engage with the yieldiiw jaws i', The .bead Q is preferably ret-esem or provided with u circular opening 2" in its end.

Combined with the head 2 is a tube 3, forming :i hollow spindle upon which a bobthin t, havin" filling 4' thereon is loosely supported. lie tube 3 is in this instance secured to the head 2 b v extendin tightly into a central openiu r through said cad.

5 is a head, o disk o'r button shape, for 50 the outer end of the spindle, and is of n diameter suti'icientto act as a bearing or race for the filling 4 as it is drawn from the bobhin, to keep it away from the end of the bobbin. The liead 5 has a reduced portion 5 u preferably of circular .sha in cross section, which is ada ted to oo-Cely enter the outer end of the tubular s indie 3.

(lne end of a spring bade 6 is attached to the reduced portion of the head and is adapted to extend loosely through the tubular spindle 3, and is provided at its inner end with the hooi: portion 6', which is adapted to extend over and engage the inner end of the tubular spindle 3, an shown in Fi 2. 16

The head 5, through tlie spring bla e 6, acts to hold the bobbin 4 on the spindle, u shown in Fig. 2. By disengaginy the hook end 6 of the blade 6 from the inner end of the spindle 3, -the head 5 is free to be re- 00 moved from the a indie, and with it the glade 6. to allow o the removal of the bob- The advantages of my improvements will he readily appreciated by those skilled in Il the art.

I provide a spindle of the description referred to. having at one end two or more annular project ions to engage the holding jaws in the spindle, and at its other. end 00 a removable tip or head, to hold tbobobbin on the spindle, and to act ns a bearing for the tillin".
